Step-by-step explanation:
Answer:
D
Step-by-step explanation:
2.75(3 x 6 - 15)= 8.25
Answer:
The estimate is not correct?
Step-by-step explanation:
Given data
Area of wall = 18*8
=144ft^2
=4*144
=576ft^2
Area of doors
=3*7
=21ft^2
=2*21
=42ft^2
Area of window
=3*5
=15ft^2
Hence the total surface area of the room
=576-42-15
=519ft^2
The amount of paint needed= 519/300= 1.73
Approximately 2 gallons
We are told that 1 gallon will cover 300ft^2
Hence 3 gallons will cover 300*3= 900ft^2
Therefore the painter overestimated the amount of paint needed
As 2 gallons will do the job
Step-by-step explanation:
-0.5x >= 4
x <= -8 (divide by -0.5, flip the inequality sign)
Hence the correct number line is the 2nd one.
An expression for the square of h is given by
.
Therefore, an expression for the product of the square of h and 8 is given by
.
